Firefox refusal/broken use of hardware acceleration.

Well, it's a different decoder - there's actually no guarantee it would have worked.

… test the behavior on X11, then you'll have to ask mozilla "wtf"
https://bugzilla.mozilla.org/show_bug.cgi?id=2054380 - but that even points out that VAAPI works using https://archlinux.org/packages/extra/x8 … ia-driver/ - probably ubuntu does the same as https://aur.archlinux.org/packages/firefox-vaapi

Tried X11, unfortunately no dice, same stuff, "TEST FAILED" error message would appear. I also tried using a different combination of about:config settings, but that wouldn't change anything, other than maybe resurrect the "NO NVIDIA LINUX" error. Definitely a big wtf moment, I'll be writing a report soon at some point. I also tried by sticking running it through "QT_QPA_PLATFORM=xcb" but that also didn't help, not that I really thought it would do anything.

I've been meaning to try put the firefox-vaapi package at some point, see if that doesn't have the issue, but ultimately, wouldn't resolve the issue anyway on Zen or Librewolf, oh well.

Firefox is not a Qt application, https://wiki.archlinux.org/title/Firefox#Xwayland
